Application filed March 4, 1922v Serial No. 541,022.

To all whom t may concern:

Be it known that I, FRANKLIN D. CHASE, a citizen of the United Sta-tes, resid-ing at Berkeley, in the count-y of Alameda and State of California, have invented certain new and useful Improvements in Flusher Boxes, of which the following is a specification.

My invention is lan improved flush tank for toilets which is simple in construction, eliminating the use of alfiush valve, eiicienlt in operation and inexpensive to manufacture. v

Referring to the annexed drawing Ain which my invention is Villustrated and which forms a part of this specilication:

Figure 1 is a plan view of my flush tank.

Figure 2 is a cross section of my Hush tank taken on line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal section of my flush tank taken on line 3-3 of vFigure 1, certain parts beingromitted.

Figure 4 is a `longitudinal section of the intake valve.

Figure 5 is an elevation of the intake valve controlling means in its valve releasing position.

Figure 6 is a view similar to Fig. 5 of said controlling means in position holding the intake valve closed.

In the drawing 1 indicates a rectangular flush tank casing, in which is journaled at its ends an elongated water receptacle 2 by means of journals 3 and 4 in the ends of said tank casing. The receptacle 2 is open at the top and a bar 5 extends across the top midway between the ends thereof. On the outer end of the receptacle journal 4 is secured a handle 6. An intake valve is mounted in and extends through the upper rear part of the left end wall of the casing 1 above the receptacle 2, said valve including a cylindrical valve casing 8 provided with an inlet 9 and an outlet 10, a valve seat 11 r in its outer end, a valve closure member 12 adapted to engage said seat, a valve rod 13 threaded at Aits rear end on which said closure member screws, and a spring 14 surrounding said rod and bearing at its ends against a shoulder 15 in said casing l and a collar 16 on said rod. The inner end portion 17 of rod 13 is slightly enlarged in diameter and is reciprocatively mounted in a bearing 18 in the inner end of the casing 8. To the outer end ,of the casing .8 `a water pipe 19 is connected by means of a coupling 20. A

Ihorizontal bracket 21 is mounted Iat yone end on the valve, a nut 22 being formed lonsaid end of said bracket which screws ona thread '2301i the linner end of the valve casing 8. A l`ever'24 :is pi-voted .at one' endlon kthe bracket y21 near the nut 22 and has a presser foot125 on its "pivolted end which Vengages the end of the porti-on 17 f the' valve rod 1:3. The other end of the lever 24 extends through a guide 26 `on the other end of the bracket21 near the bar 5 into the path of movement lof a catch 27 mounted on theupper-edge of the bar at the rear ofl the receptacle 2. A spring 28 is linterposed be, tween the lever 24 and alug `29 on the bracket 21'. A float lever 30 is pivoted lto the Aendov'f the bracket 2`1fn`ear` the bar 5, which lever carries afloat '31 on `one end and has a cam 3250.11 its other end which lrests inthe path of movement of the end .of lever 24 when the `receptacle '2' is empty and the float is down.` `A- water `inletIpipe33 is .connected to the valve outlet 10 and extends to the center of the bottom of the receptacle 2 and carries on its lower end a cage 34 which pre vents noise of the water passing from said pipe into said receptacle. A flush outlet pipe 35 leads from the bottom of the casing 1 and a sump 36 is formed in the bottom of l the casing from which leads a drain conduit into the pipe 35.

Normally the receptacle2is full ofwater and .rests lowermost but tipped backward slightly with the catch 27 in engagement with the end of lever 24, and the lever 24 swung back slightly under the influence of the spring 28 and spring 14 so that the presser foot 25 releases the end of the end portion 17 of valve rod 13 and the spring 14 holds the valve closure 12 on its seat 11, closing the y valve, while the float 31 floats in its uppermost position holding the cam 32 under the end of the lever 24.

To flush the toilet the .receptacle 2 is turned backwardly by the handle 6 and the water dumped therefrom into the tank casing 1 which passes out through pipe 35 into the toilet while the sump 36 is filled with water which passes slowly out of it through the drain conduit 37 into pipe 35 and into the toilet'. The receptacle 2 is then swung forwardly by its handle into its lowermost position, during which operation the catch 2.7 Zengages .the end of the lever 24 and swings it forwardly until said end passes over the float arm cam 32 and engages the forward edge thereof as shown in Fig. 6, (the float being down because of the discharge of the water from the receptacle 2), which movement of the lever 24 causes the presser foot 25 to engage the end portion 17 and press the valve closure 12 outwardly off its seat and open the valve 7, whereupon water passes through said valve and the pipe 33 and cage 34 into the receptacle 2. As the receptacle 2 iills with water the float 31 rises and the lever 24 escapes the cam 32 and swings backwardly under the influence of spring 28, and the spring 14, whereupon the presser foot 25 releases the part 17 and the valve closes and prevents water from entering the receptacle 2, while the receptacle 2 is tipped backwardly slightly by the engagement of lever 24 with catch 27 and is again full of water in position to have the above described flushing operation repeated.

Having described my invention, I claim: '1. A flush tank including a flushtank casing having an outlet, a water receptacle journaledwithin said casing, an intake valve mounted in said casing for controlling the admission of lwater into saidfreceptacle, a lever formed `with a presser foot for engaging the end of the stem of said valve,

a spring for swinging said lever so that said presser foot will release said valve stem. a

float lever, a float connected to said lever within said receptacle, a cam on said float lever, and a catch on said receptacle for engaging said lever and swinging it over said cam into engagement therewith into position so that said presser foot will open said valve, when the receptacle is swung back into normal position after being e1nptied, said cam being shaped to allow said lever to escape it when the oat rises to cause said spring to swing said lever to release said presser foot from the valve stem to permit the valve to open.

2. A flush tank including a flush tank casing, a water receptacle journaled within said casing, a handle by means of which the water receptacle may be tilted, an intake valve for controlling the admission of water into said receptacle, valve opening means, said means including a float, means for actuating said valve opening means to open said valve when the receptacle has been emptied and swung back into normal vposition, and means operated -by the water rising in said receptacle to hold said valve opening means in its position to open said valve, and for releasing said valve opening means when the receptacle is filled to allow said valve to close.

In testimony whereof I affix my signature.

FRANKLIN D. CHASE.
